Shaking table beneficiation is a commonly used mineral processing equipment, the basic principle is to use different ore particles of specific gravity, particle size, shape and other physical property differences, gravity sorting on a specific shaking table working surface, so as to realize the enrichment of useful minerals.

First, the structure and characteristics of shaking table

Shaking table mainly consists of bed surface, motor, speed control device, base and other parts. The bed surface is an inclined plane with a specific angle, on which there are screen mesh or grids of different specifications, which are used for supporting and conveying ore particles.

Second, the basic principle of shaking table beneficiation

The basic principle of shaking table beneficiation is to utilize the movement trajectory and speed difference of ore particles on the bed surface for sorting. Specifically, when the mixture containing different specific gravity and particle size of the ore into the shaking table, due to the bed tilt and vibration, the ore particles in the bed surface to produce different trajectories and speeds.

1. Specific gravity sorting: heavier ore particles due to the gravity of the large, along the bed sliding speed is faster, while the lighter particles sliding speed is slower. By adjusting the inclination angle and amplitude of the bed, it can realize the effective separation of ore particles with large differences in specific gravity.

2. Particle size sorting: Coarser particles are easier to roll or slide on the bed due to large particle size, while finer particles are easier to be driven by the water flow and move slowly. Through the reasonable setting of bed grid spacing and screen aperture, you can realize the effective separation of different particle size ores.

3. Shape sorting: some special shapes of ore particles in the shaking bed has special movement characteristics, such as some special surface shape of the mineral particles in the impact of water flow will produce a specific rolling or sliding behavior, these behaviors can be used for shape sorting.

Third, the application of shaking table beneficiation

Shaking table beneficiation is widely used in the beneficiation process of alluvial gold ore, tin ore, tungsten ore and other metal mines, as well as some non-metallic ore separation. Through shaking table beneficiation, it can effectively enrich the useful minerals and improve the mining efficiency of the mine.

In a word, shaking table beneficiation equipment utilizes the difference of physical properties of ore particles, and carries out gravity sorting through the specific shaking table working surface, so as to realize the enrichment of useful minerals. Its basic principles include specific gravity sorting, particle size sorting and shape sorting in various ways.
